Wiki info about LaGG-3-35

Together with two other fighters, this Soviet single-engine fighter replaced the obsolete I-16 and I-153, which at that time were the core fighters of the Soviet Air Force's RKKA. The LaGG-3 began appearing on the aviation scene in early 1941, several months prior to the beginning of the Great Patriotic War, and was manufactured at Lavochkin-Gorbunov-Goudkov until 1944.
In terms of armaments, the LaGG-3 carried two 12.7 mm Berezin BS machine guns, one 20 mm SHVAK cannon and six RS-82 or RS-132 rockets. In addition, bombs aboard the LaGG-3 could be suspended. Throughout its production, Lavochkin-Gorbunov-Goudkov manufactured dozens of variants of the more than 6,200 LaGG-3s it built.
